At Contaminex, we believe in clear communication about how we use tracking technologies on our online education platform. Our approach balances the need for effective learning tools with privacy and transparency. This document explains the types of tracking we use, why we use them, and how you can manage your preferences. We want you to feel informed about the choices you have while using our services.
Digital tracking tools serve several roles on Contaminex. These include making sure our platform works as intended, improving your experience, and helping us provide content that’s relevant to each learner. We use a mix of cookies, local storage, and analytics scripts, among other methods. Most of these operate by storing small identifiers or preference information in your browser or device. Some are temporary, lasting only as long as your session, while others remain between visits to keep your experience consistent.
Some tracking methods are absolutely necessary for the platform to work. For example, our authentication cookies remember when you’re logged in, so you don’t get logged out in the middle of a lesson. If these are blocked, you wouldn’t be able to access your courses or save your progress. For quizzes and interactive modules, session storage helps us keep track of your answers so you can pick up right where you left off, even if you accidentally close your browser.
Analytics tools collect a wide range of non-personal metrics, such as which lessons are most popular, how long students spend on activities, and where learners tend to drop off. We look at patterns like how many people finish a certain module or whether students revisit specific topics. This information helps us improve course materials, spot confusing sections, and provide instructors with insights to support their students. For example, if a video tutorial has a high abandonment rate, we might review its content for clarity.
Functional tracking technologies focus more on your individual preferences. For instance, we use them to remember if you prefer dark mode, what language you selected, or even the order in which you like to see your courses. If you use accessibility features—such as larger text or color contrast adjustments—we save these settings so you don’t have to reapply them every visit. This kind of personalization makes learning smoother by reducing repetitive setup steps.
Customization features build on this, tailoring the learning journey to your interests and goals. For example, if you tend to focus on biology courses, our algorithms might highlight new biology modules or suggest related quizzes. Instructors can receive recommendations about supplemental resources based on class engagement patterns. These features help make the content you see more relevant and engaging, letting you get the most out of your time on Contaminex.
The entire technology ecosystem works together in a kind of digital symphony. Essential cookies keep your session alive, while analytics scripts quietly gather insights in the background. Personalization engines connect your past activity to future recommendations, and functional tools remember the little details that make the platform feel familiar. For example, after you finish a course, you might see a suggestion for a related topic—powered by a combination of your preferences, learning history, and broader site trends.
You have a range of options to control how tracking works on Contaminex. Laws like the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) give you certain rights, including the ability to refuse non-essential tracking and to request deletion of stored data. We encourage you to explore these controls so you can tailor your privacy settings to your comfort level.
If you want to manage tracking through your web browser, most major browsers let you review, block, or delete cookies and other trackers. For example, in Google Chrome, you can go to Settings > Privacy and Security > Cookies and other site data to view and adjust cookie permissions. In Mozilla Firefox, navigate to Settings > Privacy & Security > Cookies and Site Data. Microsoft Edge users can find similar controls under Settings > Cookies and site permissions. Each browser also lets you clear existing data, which can be helpful if you want to start fresh or after making changes to your settings.
Contaminex provides its own preference center for managing tracking and privacy choices. You can access this via your account settings menu. Here, you’ll see options to opt in or out of analytics tracking, personalization features, and functional cookies. Just follow the on-screen instructions—changes take effect immediately, although you may need to refresh your browser for some adjustments to apply.
Disabling certain categories of tracking may affect your learning experience. For instance, if you turn off functional cookies, your language preferences or accessibility settings may not be remembered, requiring you to set them each visit. Blocking analytics won’t stop you from accessing content, but it does mean your usage data won’t contribute to improving the platform. Opting out of all non-essential tracking may result in a less tailored experience, with more generic recommendations and fewer personalized features.
There are also third-party tools you can use. Extensions like Privacy Badger or browser-based tracker blockers give fine-grained control over which scripts can run on your device. For those particularly concerned about privacy in educational settings, the Electronic Frontier Foundation provides guides on balancing privacy with learning needs. Keep in mind that some blockers can interfere with interactive content, so you might need to whitelist Contaminex for the best experience.
Finding the right balance between privacy and functionality is often a personal decision. If you’re primarily interested in privacy, you might prefer stricter settings—even if that means a few extra clicks for login or setup. On the other hand, if you want the most streamlined learning journey, allowing functional and customization features can save you time and help you focus on what matters: your education. We encourage you to experiment and see what works best for your workflow.
Not all data is kept forever. Session cookies, for example, are deleted automatically when you log out or close your browser. For analytics data, we generally retain information for up to 26 months, after which it’s either deleted or aggregated in a way that can’t be tied to individual users. User preferences and account-related settings are kept as long as your account is active, but are removed permanently after you delete your account or request erasure.
Protecting your data is a responsibility we take seriously. Our technical safeguards include encryption both in transit and at rest, regular vulnerability scans, and strict access controls for staff. Organizational measures—such as mandatory privacy training and incident response plans—help keep everyone accountable. We also audit our systems regularly to ensure compliance with our internal protocols.
Sometimes, the data we collect through tracking is combined with other sources to provide a more coherent learning experience. For example, analytics about your quiz performance might be paired with your course completion history to suggest new challenges at the right difficulty level. If you’ve connected your account with external education services, certain information—like your course credits or certifications—may be imported to personalize your learning path further.
Our privacy practices are designed to align with major legal frameworks. For users in the European Economic Area, we follow the GDPR’s requirements for consent, transparency, and data access. In the United States, we comply with the CCPA and related state-level laws, including offering clear opt-out options and honoring “Do Not Track” signals where supported. Periodic reviews help us keep our policies up to date as laws evolve.
We recognize that certain users—especially younger learners—require extra care. For accounts registered as belonging to minors, we limit the types of data collected and disable non-essential tracking by default. Educational content is filtered for age-appropriateness, and instructors or guardians have additional controls over privacy settings. We also provide clear explanations of privacy choices in language suitable for younger users.
Contaminex works with a carefully selected group of external partners who help us deliver and improve our educational services. These may include analytics providers, content delivery networks, and specialist education tool developers. We don’t allow advertisers or unrelated third parties to collect data on our platform.
